This is an addendum to Adolf Harnack "Marcion: Das Evangelium vom fremden Gott". For some reason in the above file 6 pages were missing, which are given in this addendum. If you have a PDF editing program like Adobe Acrobat Pro, you can insert the images into the original file.
The missing pages are: 17, 186, 61*, 86*, 159*, 244*.
To make it even more complete, I am adding Harnack's article
"Neue Studien zu Marcion" Leipzig, 1923
Texte und Untersuchungen 3. Reihe 14. Band, Heft 4
